LM 2 was built for a second unmanned Earth-orbit test flight. Because the test flight of LM 1, named Apollo 5, was so successful, a second mission was deemed unnecessary. LM-2 was used for ground testing prior to the first successful Moon-landing mission. In 1970 the ascent stage of LM-2 spent several months on display at the "Expo '70" in Osaka, Japan. When it returned to the United States, it was reunited with its descent stage, modified to appear like the Apollo 11 Lunar Module "Eagle," and transferred to the Smithsonian for display in the National Ai rand Space Museum's Lunar Exploration Vehicles gallery.
